The 51 Series single-chip MCU is the most typical and most representative one.
而51系列单片机是各单片机中最为典型和最有代表性的一种。
Also known as single-chip MCU (Microcontroller), because it was first used in the field of industrial control.
单片机也被称为微控制器(Microcontroller)，是因为它最早被用在工业控制领域。
Therefore, the clock frequency directly affect the speed of MCU, clocking circuit and the quality of directly influence the stability of single-chip microcomputer system.
因此，时钟频率直接影响单片机的速度，时钟电路的质量也直接影响单片机系统的稳定性。
